Study on the Temperature Rise Test Method of Mine Flameproof Combined Starter
The mutual influence of heat generation and heat accumulation law between circuits when the mine explo-sive isolation combination starter is working normally and the difference between three-phase current application method and single-phase series current application method specified in the standard are studied,and two test schemes of three phase current application method and series current application method,which meet the standards and implementation rules,are proposed,including seven current application methods.The QJZ-1600/1140(660)-8M mine explosion-proof and intrinsic type multi-circuit vacuum electromagnetic starter is used to carry out the com-parison test,and the optimum current application method and loading circuit position for the temperature rise mea-surement test are finally obtained.
